Skin Disorders

Published on 28th September 2020


As part of your anatomy and physiology course, you need to study pathologies. (That's diseases and disorders to you and me!)

The human body is designed to be in a state of ease, but if not treated well with good nutrition, exercise, relaxation and good thoughts the body can become out of balance and a state of dis-ease or disease results. A disorder is when there is irregularity, disturbance, or interruption of normal functions in the body. For example the bsence of a woman's monthly menstrual period not due to pregnancy called be a disorder and is called amenorrhea. A sprained ankle is an injury and a curved spine is a disorder. 

Here are a couple of pathologies for the Skin
